Question

Accepted Answer

A double linked list is a data structure where each node contains a reference to the previous and next node.

In a linked list, each node contains a reference to the next node only, while in a double linked list, each node contains references to both the previous and next nodes.
Double linked lists allow for traversal in both directions, making operations like deletion and insertion easier compared to single linked lists.
Example: In a double linked list, a node might have pointers to the previous node and the next node, allowing for bidirectional traversal.
